unsigned char Cmd[]= {0x40, 0x40, 0x00, 0x00, 0x0b, 0x01};



为什么里面的值相加不了？ Cmd[0]+Cmd[1]...就会提示 subscript requires array or pointer type

为啥啊 不懂

unsigned char Cmd[]= {0x40, 0x40, 0x00, 0x00, 0x0b, 0x01,
                     0x04,                            //0x03 相对位移 0x04绝对位移
                     0,                                //10，20，30，40，50，60 轴号
                     0, 0,                            //加速度
                     0, 0, 0, 0,                    //速度
                     0, 0, 0, 0,                    //位移
                     0,                                //标志位
                     0x23, 0x23};   



unsigned char AddSum, SpeedSum, ShiftSum, CmdSum;
CmdSum = 0;   

    for(k=4;k<7;k++)
    {
        CmdSum +=Cmd[k];  
    }

E:\vcProgram\AllLed\AllLedDlg.cpp(732) : error C2109: subscript requires array or pointer type
E:\vcProgram\AllLed\AllLedDlg.cpp(732) : error C2297: '+=' : illegal, right operand has type 'void (__thiscall CAllLedDlg::*)(unsigned char *)'   

错误指向      CmdSum +=Cmd[k]; 这一句。
